public class OnHeapH3IndexCreator
extends BaseH3IndexCreator

H3 Index creator that uses on-heap memory.

On-heap creator uses more heap memory, but is cheaper on computation and does not flush data to disk which can slow down the creation because of the IO latency. Use on-heap creator in the environment where there is enough heap memory and garbage collection won't cause performance issue (e.g. Hadoop/Spark/Pinot Minion).
